BuildHooksEnv(self)

source code

Build hooks env.

This doesn't run on the target node in the pre phase as a failed node would then be impossible to remove.

Returns: dict: Dictionary containing the environment that will be used for running the hooks for this LU. The keys of the dict must not be prefixed with "GANETI_"--that'll be added by the hooks runner. The hooks runner will extend the environment with additional variables. If no environment should be defined, an empty dictionary should be returned (not None).
Overrides: LogicalUnit.BuildHooksEnv

BuildHooksNodes(self)

source code

Build hooks nodes.

Returns: tuple; (list, list): Tuple containing a list of node names on which the hook should run before the execution and a list of node names on which the hook should run after the execution. No nodes should be returned as an empty list (and not None).
Overrides: LogicalUnit.BuildHooksNodes

CheckPrereq(self)

source code

Check prerequisites.

This checks:

the node exists in the configuration
it does not have primary or secondary instances
it's not the master

Any errors are signaled by raising errors.OpPrereqError.

Overrides: LogicalUnit.CheckPrereq

Exec(self, feedback_fn)

source code

Removes the node from the cluster.

Overrides: LogicalUnit.Exec
